Free Companies API
The Companies API offers a powerful B2B dataset containing information on millions of global enterprises. Use this API to enrich leads, perform market research, build investment dashboards, or map out organizational hierarchies.
What is a REST API?
An API (Application Programming Interface) allows two software programs to communicate. A REST API uses standard HTTP requests like GET (to read data), POST (to create data), PUT (to update), and DELETE (to remove).
When you send a request to our https://techidea.online/api/v1/companies endpoint, our server responds with a JSON (JavaScript Object Notation) array containing data. You can then display this data in your frontend React, Next.js, or mobile applications.
